Abstract

CdS is II-VI semiconductor with a wide band gap of approximately 2.42 eV. CdS is the most popularly employed heterojunction partner to p-CdTe due to its similar chemical properties. In this work, to improvement of the surface properties of the CdS films, PET substrate is treated by high density $O_2$ plasma. CdS films are prepared by chemical bath deposition(CBD) method. In case of the PET substrate with plasma treatment for 2min, the crystalline orientation of CdS films exhibits a strong hexagonal(002). Grain size was increased from 300nm without $O_2$ plasma treatment to 380nm with an $O_2$ plasma treatment.
